Description
Die Erfindung betrifft einen Detektor zum Nachweis und zur Messung elektrischtr Schwingungen, vorzugsweise im Gebiet kürzester Wellenlängen. Wenn man hei der Gleichrichtungg eines hochfrequenten Wechselstromes mittels eines Detektors eine hohe Richtspanfiung erreichen will, dann muß man dafür sorgen, daß die Resonanzfliequenz des Detektorgebildes möglichst hoch liegt, d. h. man Inuß sowohl seine Kapazität als auch seine Induktivität möglichst herabzusetzen suchen. Die Erfindung betrifft nun eine Detektorkonstruktion,' bei welcher eine Verkleinerung von Kapazität und Induktivität auf ein Mindestmaß in sehr (einfacher, herstellungstechnisch vorteilhafter Weise erreicht ist. Erfin,dungsgemäß, ist dic Diebektorfeder an einem vorzugsweise zylindrischen, zur Kristalloberfläche im wesentlichen senkrechten Haltestab befestigt, der in Ader Richtung nach der Detektorspitze zu verjüngt ist. Wie die' Konstruktion praktisch am besten ausgeführt wird, läßt sich aus der Zeichnung entheInnen. In dieser bedeutet i den im vorliegenden Fall zylindrischen Kristallträger mit dem. Kristall 2. Der Kristallträger i ist in ein Keramikrohr 3 oder ein Rohr aus einem anderen Isoherstoff eingesetzit# z. B. eingelötet. Zu. diesem Zweck gibt man dem Ker.amikrohr 3 einen Metallüberzug, der z. B. in Pulverform (mit (einem Bindemittel) aufgebracht und in. die Kexamikoberfläche eingebrannt wird. Ein solcher überzug ist sehr gut für 'die Hartlötung geeignet. Gegenüber dern Dietektorkristall 2 stellt die auf dem Spitzenträger 4 befestigte Dietektorspitze 5. Der Spitzenträger 4 ist aus #drei Abs,ätz,en gebildet. dem ül das Keramikrohr ieinge-1,5teten Stab 6 und zwei Ansätzen 7 und 8, welche derartige Durchmesser haben, daß sich eine Verjüngungdes Trägers in Richtung der Detektorspitze ergibt. Zur Stromleitung dient also der Stab 6- (mit seinen Ansätzen), dessen Durchmesser ein Vielfaches des Durchmessers der Detektorfeder beträgt, die Induktivität ist also klein. Eine weitere Wrbesserung in - dieser Richtung erzielt man dadurch, daß n= einen, und zwar am besten den größten Teil der Feder um den Ansatz 8 fest herumwickelt, dann fällt nämlich noch die Induktivität eines -roßen Teiles der Feder wez. Die Kapazität wird dabei fast ausschließlich durch das Fed#rende (die Detektorspitze) bestimmt, da der Spitz-enhalter infolge seiner Verjüngung zu der Kapazität praktiscli nichts heiträgt. Es gelingt also auf dies,(,-Weise, die Induktivität und die Kapazität gleichzeitig sehr klein zu, halten. Dabei ist ab-er auch die Gesamtanordnung sehr einfach. Der Detektor besteht aus wenigen, aber einfach herstellbaren. Teilen, die durch Löten zu einem haltbaren, geschlossenen Gebilde vexeinigt werden können.The invention relates to a detector for detecting and measuring electrical vibrations, preferably in the area of the shortest wavelengths. If you want to achieve a high directional voltage when rectifying a high-frequency alternating current by means of a detector, you must ensure that the resonance flux of the detector structure is as high as possible, i.e. H. one must try to reduce both its capacitance and its inductance as much as possible. The invention now relates to a detector construction in which a reduction in capacitance and inductance to a minimum is achieved in a very simple and advantageous manner in terms of production. which is tapered in the direction of the detector tip. How the construction is practically best carried out can be seen from the drawing, in which i means the crystal carrier, which is cylindrical in the present case, with crystal 2. The crystal carrier i is in one Ceramic tube 3 or a tube made of another insulating material, e.g. soldered in. For this purpose, the ceramic tube 3 is given a metal coating, which is applied, for example, in powder form (with (a binding agent)) and into the ceramic surface Such a coating is very suitable for brazing. Compared to Dietekt Orkristall 2 represents the Dietektor tip 5 attached to the tip carrier 4. The tip carrier 4 is made up of three abs, etching, en. the rod 6 , which is inserted into the ceramic tube, and two lugs 7 and 8, which have such a diameter that the support is tapered in the direction of the detector tip. The rod 6- (with its attachments), the diameter of which is a multiple of the diameter of the detector spring, is used to conduct electricity, so the inductance is small. Another Wrbesserung in - is achieved that direction characterized in that n =, though firmly wraps and a best the largest part of the spring around the neck 8, then the inductance falls namely, a part of the spring -roßen wez. The capacity is almost exclusively determined by the end of the spring (the detector tip), since the tip holder has practically nothing to do with the capacity due to its taper. In this way, it is possible to keep the inductance and the capacitance very small at the same time. At the same time, the overall arrangement is also very simple. The detector consists of a few, but easy-to-manufacture parts, which are closed by soldering can be combined into a durable, closed structure.
